A.D.S. Behemoth

An immense starship once built by the Alti Dominion. A.D.S. Behemoth was a huge contruction project for a faction of that size - rivalling a Hyperion - Class Worldship Carrier in sheer size. A.D.S. Behemoth would be designed primarily for military uses, rather than as civilian uses like the Hyperion - Class. As such, the behemoth mounted significantly larger weapons. Like all Alti starships, the Behemoth mounted huge railguns - exceptionally powerful - but with a very high fire rate despite the huge energy draw. It would be the Hyperion Federation that would detect it first. Although no other faction found out about the project until it was found by the HF, the HF managed to find it well within the borders of the Alti Dominion. They sent a fleet of Lurker - Class Subspatial Starships to destroy it, staying submerged while within Alti territory. Although the Behemoth suffered damge, it was repaired and intercepted most of the torpedoes fired at it.
"I said I wanted it big. It only makes sense for the largest superpower in the Galaxy to have the largest super dreadnaught in space, right? What do you mean, there is a fleet of blue glowing ships storming our territory with titans twice the size of our own?"
